Thanks Roy for your answer (and not being provocative). And thanks phil for summing it up and moving on from all the technicalities; it's down to what you "feel", isn't it.
My second question was why haven't the majority of "surfboard" shaper didn't follow, as Roy states, the secret weapon of thick, rounded nose but decided to follow pointy, thinner nose?
Theoretically speaking it may make sense? to have thicker rounder nose for "aerodynamic" aspect, but maybe its impractical when duck diving...?
maybe it's easier to shape pointy nose compared to rounder nose (would weeder shapers agree with this?)?
maybe pointier (narrower) nose helps the rider to paddle more efficiently (shoulder roll)?
maybe it just doesn't look cool (back to fashion answer)?
or maybe we haven't fully understood the influence of aerodynamics in surfing (and copyright speedoprene)...
I maybe wrong but I'm seeing the "shorter, wider, stubbier" trend in board shapes, would be interesting to see how the "nose" shape develops.
